signal processing applications, while reducing system complexity and
board space.

NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. (NASDAQ: ADI) released today a synchronous
demodulator with the industry’s best combination of integration,
performance, flexibility and power consumption.
The ADA2200 uses ADI’s patent pending sampled
analog technology (SAT), developed at Lyric Semiconductor, Inc.
(acquired by ADI in mid-2011), and incorporates a configurable analog
filter to enable designers of portable and low-power instrumentation to
maximize battery life and perform precision magnitude and phase
measurements on analog signals in the presence of large noise sources.
Compared to traditional discrete implementations, this compact,
integrated solution reduces PCB area by up to 25 percent and provides
designers with a higher degree of flexibility, reducing system design
and optimization time and facilitating circuit design reuse across
multiple sensors, products and platforms.
The low-power (390-uA at 3.3V and fCLK = 500 kHz) and
rail-to-rail operation of the ADA2200 make it ideal for advanced
battery-powered and low-voltage systems serving medical, industrial and
communications markets and can be used in a wide variety of applications
including impedance measurement, gas detection, air or fluid analysis,
strain gauges and proximity measurement.
About The ADA2200 and Patent Pending SAT Technology
The
ADA2200 features a highly integrated analog signal chain, including a
configurable infinite impulse response (IIR) filter, low-pass finite
impulse response (FIR) 1/8x decimation filter, mixer with 0°/90° phase
selection, reference clock and A/D converter driver output. Optimized
for input sampling rates up to 1 MHz, the ADA2200 enables demodulation
of signal input bandwidths to 30 kHz, achieves 0.009º phase detection
sensitivity and operates over a -40°C to +85°C temperature range.
ADI’s proprietary SAT technology uses charge sharing among capacitors to
perform “digital-like” computations in the analog domain. By processing
the signal entirely in the analog domain, this analog-in,
sampled-analog-out device reduces A/D converter sample rates, lowering
A/D converter power consumption by up to 87 percent and offloads
computationally heavy tasks from the digital processor or
microcontroller. This allows designers to simplify their system
architecture, shorten development time, and reduce system size and power
consumption.
